Long Island boy kills mom's ex-boyfriend in home invasion

MASTIC BEACH (AP) – Police on eastern Long Island say a 13-year-old boy coming to his mother’s defense fatally stabbed her ex-boyfriend after he entered their home in the middle of the night.

The incident happened Monday in Mastic Beach.

Suffolk County police say 48-year-old Norman Shields, who has a history of violent felonies, threatened 31-year-old Natasha Bivens with a gun. Bivens is the mother of their 4-year-old daughter from a prior relationship.

Shields confronted Bivens and her new boyfriend at about 3:45 a.m. in her home on Selden Road.

Homicide detectives say when Shields fired a shot her young son intervened and stabbed the man.

He was later pronounced dead at Brookhaven Memorial Hospital.

Police said that the teenager is not currently facing charges. The investigation is ongoing.
